Patent ES-366796-A1 (ES)
Title: Ignition devices
IPC: F23Q1/02
Filed: 1969-05-05
Abstract: An ignition device comprises a rod slidable longitudinally within a cylindrical housing, and a detachable flint, extending transversely of the housing and biased by a spring into contact with a roughened surface, e.g. having projections or threaded, at one end of the rod, so that movement of the rod by a handle at its other end, external of the housing, produces sparks, and a cylindrical part provided with a window is screwed into the housing at an oblique angle to its longitudinal axis for viewing the sparks. A pin may be inserted through, and locked in, the housing to engage in an annular groove about an inward extension of the handle to prevent movement of the rod, and rings mounted on the rod define the limits of its movement in operation. In a flare stack burner the interior of the housing is in direct communication with a by-pass channel supplied with a compressed mixture of air and gas at a reduced velocity from a main channel. The channels re-unite and pass to a distributer so that gas may be selectively passed to any one of three pilot burners about the flue stack mouth and ignited by the device. The housing is screwed into the side of the by-pass channel and interengaging parts on the by-pass channel and the part holding the flint may be provided to ensure that the flint is removed before the housing is unscrewed. In a modification, the device is disposed in the main channel and provided with a shield to reduce the local gas velocity.

Title: Reflector device
IPC: F21V29/505
Filed: 1969-11-11
Abstract: A device for reflecting electromagnetic radiation from an elongated radiation source comprising a profiled holder formed as a body having a cavity that provides a supporting surface for a reflecting metal strip.

Patent ES-377684-A1 (ES)
Title: Antilocking control for pressure actuated brakes
IPC: B60T8/42
Filed: 1970-03-18
Abstract: The pressure of the brake-actuating fluid in an antilocking brake control system is varied by pulsing the control valve or valves for durations which are varied to be greater or lesser than the period of that limiting frequency above which the brake system can not respond. In the former case, a rapid increase in fluid pressure or a rapid decrease in fluid pressure occurs, whereas in the latter case, a less rapid average or net increase or decrease in fluid pressure to which the brake system responds occurs. These conditions are controlled in dependence on the rotational behavior of the vehicles wheel or wheels and more especially in dependence on predetermined changes in angular velocity of the wheel. Moreover, either variation in pulse duration at fixed frequency or variation in frequency at fixed pulse duration may be effected during high-frequency pulsing so as further to alter the net increase or decrease in fluid pressure. This further alteration is effected as a function of time from the beginning of the high-frequency pulsing.

Title: Woven and braided furniture
IPC: D03D41/00
Filed: 1973-12-28
Abstract: A portion of a woven piece of furniture is provided with a braided periphery integral with the warp of the weave and transverse thereto. The warp strands extend beyond the weave and are braided so that each strand changes directions at least twice to form a generally S-shaped curve and the strands are periodically severed at this time. One or more support strands alone or in a pair are incorporated into the braid during the method to increase the structural strength and improve the appearance of the braid. A braid formed longitudinal to the warp strands and integral with the foregoing transverse one is formed by mounting a plurality of adjacent extending engaging strands in a frame member and braiding strands projecting from the transverse braid together with the engaging strands. A particularly suitable strand material is known in Italy by the name "secca". A variety of attractive braids are formed in the above general manner.

An override circuit is responsive to the pressure detector and an override set point input to produce an override output for controlling the induced draft fan at a rate substantially higher than that of the correction signal. There is also provided a transfer and memory circuit responsive to combustion air flow to the furnace and a furnace trip condition such that the circuit produces a signal to modify said fan control signal in accordance with the actual air flow to the furnace and in anticipation of an inevitable furnace pressure excursion caused by said furnace trip.

Title: Reservoir assemblies for vehicle braking systems
IPC: B60T11/26
Filed: 1976-09-23
Abstract: In a reservoir assembly for a tandem master cylinder of a hydraulic braking system the container is separated into compartments by at least one baffle passages being provided for permitting limited communication between the compartments past the baffle.
